Abstract
The invention relates to a waste and old tyre powder modified asphalt grinding machine. The grinding machine comprises one of a cylinder stone roller bearing or a needle roller bearing or a radial thrust bearing, a mechanical pump shell (sleeve I and sleeve II), a spring, a retainer ring, a fan, a thrust rod, a rotating shaft, a round head guiding flat key and a silicon sealing ring, wherein a bearing inner race is connected to the rotating shaft of a high temperature electric motor, a bearing outer race is installed on the thrust rod, and the mechanical pump shell is provided with a feeding port and a discharging port. The grinding machine is characterized in that a centrifugal self-absorption blade is also connected with the rotating shaft of the high temperature electric motor, when the high temperature electric motor rotates, the self-absorption blade presses materials to a rolling element between the bearing inner race and the bearing outer race, meanwhile, and the bearing inner race of a connecting shaft of the high temperature electric motor also rotates at a high speed and drives the rolling element between the bearing inner race and the bearing outer race to rotate at a high speed, therefore the waste and old tyre powder in the high temperature asphalt flowing through the rolling element is continuously grinded and refined, and the aim of rapid dissolution is reached.
Description
Technical field
The present invention relates to the process equipment of a kind of construction material----pitch.
Background technology
Along with advancing by leaps and bounds of highway in China construction; The pump priming that particularly country takes after financial crisis last year; A large amount of investments pours in high ferro, highway, makes highway and the belt express passway of China on average be open to the traffic with annual 2000 kilometers progress, and the year use amount that is used to build important the construction material----pitch of highway breaks through 5,000,000 tons; Wherein, the use of modified pitch is near 3,000,000 tons.
Existing modified pitch production, additive adopts oil product basically---thermoplastic body elasticity body SBS, its advantage is the SBS steady quality as additive, but it has two fatal weakness:
1. general SBS, its solution temperature>=180 ℃, and the pitch heating-up temperature requires≤180 ℃, the pitch heating-up temperature in a single day>=180 ℃, pitch can be aging rapidly, can emerge simultaneously contains the tobacco of benzene, very big to human harm.Thereby with SBS as the Additive Production modified pitch, working condition is very harsh;
2. do the Additive Production modified pitch with SBS, production cost is higher.The price of SBS between 16000 yuan～26000 yuan, the addition by 4%, 1 ton of modified pitch of every production will rise 640 yuan～1040 yuan than the matrix pitch cost.
And if do modification and produce modified pitch with the junked tire powder, just in time can remedy to make and change the weakness that modified pitch is produced in the surname agent of SBS:
1. general junked tire powder, its solution temperature only need>=140 ℃, and the pitch heating-up temperature is only required≤180 ℃, the temperature scope of compromise than broad is arranged in the last product;
2. junked tire powder market price is pressed 10% addition about 2000 yuan, and 1 ton of modified pitch of every production rises about 200 yuan than the matrix pitch cost.
The recoverable amount of the annual automobile of China is with greater than 10% speed increment, and a large amount of junked tires of generation are extremely disadvantageous to environmental protection.
The present invention will invent a kind of equipment exactly, can use the junked tire powder as the Additive Production modified pitch.
The grinding machine of existing production junked tire powder-modified asphalt is representational to be the colloid mill of axle head fluted disc, when material gets into slot, cuts, and different is the number of teeth of cutting and the size in slot crack, makes the granularity of material finally reach requirement.But do not have suction capacity to need the outside front pump that is equipped with same traffic to work, can produce very big cutting heat at work, energy consumption is very big, and the Process configuration cost increases, and price is very expensive.According to about 200,000 dollars of the about needs of the difference of flow.
In fact in the production of junked tire powder-modified asphalt main production difficult point be how with the junked tire powder equably dispersing and dissolving in pitch; Dissolving just will be convenient in the order ground of refinement; And be not that the dissolving of refinement more is just fast more; Certain effect of fluxing is arranged, but the dissolving of junked tire powder time definitely, if in other words with very thin colloid mill can not overground back just directly entrucking use; So need the junked tire grinding not got too thin aborning; The junked tire powder that when pitch reaches 140 ℃, mixes at high temperature has been the rubber bodies of softening, and can produce a large amount of cutting heat and extremely stretch with the colloid mill in finedraw crack too softening rubber bodies, causes product ductility index unstable.
Summary of the invention
The objective of the invention is to carry a kind of confession junked tire powder-modified asphalt grinder, it has following advantage: 1, low power consuming: only need the power consumption of 1/3 colloid mill; 2, have suction capacity, need not to dispose in addition delivery pump; Simplify the production technology configuration, lowered cost of investment; 3, lapping apparatus adopts finished product bearing on the market, and price is extremely cheap, has only about 1/10 of common colloid mill price; 4, there is not the generation of a large amount of cutting heats.
